ADJUSTABLE SASH WEGHT.

Application led August 10, 1922. Serial No. 580,962.

T 0 all whom t may concern:

Be it known that l, Geenen A. DicnINsoN, a citizen of' the United States, residing at Davenport, in the county ot Scott and State ot lowa, have invented. certain new and usetul lmprovements in Adjustable Sash Vlleights, ot which the following is a speci`.

ication.

This invention relates to window sashes, and the primary object ot the invention is to provide an improved sash weight embodying novel means 'for permit-tino the weight of the body thereof to be conveniently changed to conform to the weight ot the window sash to be balanced.

Another object of the invention is the provision oit an improved sash weight embodying a body having a longitudinally eX- tending pocket 'termed therein opening out at one longitudinal tace thereof, the pocket being adapted to receive small weight segments to -permit the weight ot the body to be changed.

A further object ot the invent-ionis to provide novel means tor associating the small weight segments with the body ot the sash weight so as to permit the weight segments to be readily and quickly associated ywith or removed from the body of the sash weight and to prevent accidental displacement ot the segments when the sash weight is in use.

A further object of the invention 1s the provision ot an improved adjustable sash weight embodying a body having a longitudinally extending pocket formed therein opening out at one longitudinal tace thereof tor the reception ot small weight segments and means termed on the lower end thereof for detachably supporting a relatively large weight segment, the body ot said sash weight being so constructed as to permit the simul taneous use ot' any number of small weight segments and the relatively large weight segment.

A still further object of the invention is the provision ot an adjustable sash weight of the above character, which will be durable and etlicient in use, one that will be simple and easy to manufacture, and. one which can be placed upon the market at a reasonable cost.

`With these and other objects in view, the invention consists in the novel construction arrangement and formation of parts, as will. hereinafter more specifically described,

claimed and illustrated in the accompanying drawings. forming a part of this specification, in which drawing:

Figure 1 is a fragmentary perspective view of a window trame showing the improved sash weight incorporated therewith.

Figure 2 is an enlarged perspective view or" the improved sash weight showing the relatively large weight segment connected to the body of the weight and one of the relatively small weight segments positioned in the pocket formed in the body ot the weight.

Figure 3 is a fragmentary detail perspective view of the lower portion ot the body ot the improved sash weight.

Figure l is a detail perspective view ot the relatively large weight segment.

Figure 5 is an enlarged fragmentary longitudinal section through the upper end ot the body portion ot the sash weight, showing the means of connecting the pulley for the sash cord therewith.

Figure 6 is a detail plan view of one of the relatively small sash weight segments.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the severa-l views, the'letter A generally indicates the improved sash weight and B a window trarne or casing, with which it can Vbe associated.

rl`he window frame or casing B forms no part oli' the present invention but has merely been shown to illustrate the use et the improved weight, and as shown in the drawings, the casing or trame B includes the usual pulley stiles 10, which support the pulleys 11 and 12 for the sash cord 18. on which the sash weight A. is hung. The sashes 1li and 15 are mounted in the usual manner within the window 'trame B.

The improved sash weight A comprises a body 16 having its upper end. slotted or bifurcated as at 17 ttor the reception of the pulley 18 around which is adapted to be trained the sash cord 13 for the sashes 14 and 15. A suitable pin 19 is carried by the upper end ot the body 1G tor rotatably supporting the pulley. A longitudinally eX- tending pocket 20 is formed in the body 16 below the biturcated or slotted portion 17 and this pocket opens out through one of the longitudinal side faces of the body as clearly shown in Figures 2 and 3 of the drawings. lit is also preferred that the said pocket open out through. the lower end of the body,

and this pocket deiines a rear Wall 21, side Walls 22, and a top Wall The lon-'er terminals of the side Walls 22 are provided with inwardly extending lugs 2li which form a support for' the relatively large Weight segment C and a stop for the relatirely small Weight segments l). 1t is preferred that the upper edges of the lugs 24 be provided with semi-circular notches 25 for forming bearings, as will be hereinafter more fully described. rl'hs loiver faces of these lugs, as Well as the side Walls 22 terminate `in an arcuate plane to form arcuate bearing faces 26, the purpose of Which also ivill be hereinafter more fully described.

Disposed Within the pocket 2O andy formed integra-l With or connected to the rear Wall 21 is the longitudinally extending centrally disposed guide rail 2T. This guide rail is of` a dove-tail shape in transverse section and terminates short of the top vra-ll of the pocket 2O as indicated by the reference character 28. This guide rail 2T can extend to the eXtreme loiver end of the pocket 2O if so desired', as clearly shown in Figure 3 of the drawings. Y

The relatively large segmental Weight C includes a solid body 30 havinf;` its upper edge concaved as at 31 which conforms to the arcuate bearing surfaces 26 of the lower end of the body 16 of the sash ivc'ght The upper end of the relatively large Weight segment C is provided with a pair of spaced upstanding arms 32 which are adapted. to fitr Within the pocket 2O in facial. abutment With the lugs 24. The upper terminals of the arms 32 have their outer side faces provided ivith semi-cylindrical bearing pins 33, which are adapted to lit Within the semicircular shaped bearing notches 25 formed on the bearing lugs 24. Thus, inlassociating the segmental Weight C with the body 16 of the sash A., the segment C is held at right angles to the body 16 and pushed inwardly until the semi-cylindrical bearing pins 33 rest above the bearing notches 25 at which time the Weight segment C can be swung down parallel With the body 16 and the semi-cylindrical bearing pins Will drop into the semi-circular bearing` notches 25. The connection of the segmental Weight C of course,r adds Weight to the sash TWeight A as is readily apparent.

The relatively small Weight segments D each consist of a fla-t body 40 having the inner edge thereof provided with a dove tailed groove 41 for the reception of the dove tailed guide rail 27. In associating a relatively small Weight segment D With the body 16 ofthe sash Weight. the same is disposed in the upper end of the pocket 20 and pushed inwardly until the dove tailed groove 41 is directly above the rail 27, at which time the Weight can be pushed downward Within the pocket on the rail 27., It can be seen'that the upper faces of the lugs 24C will form stops for the relatively small Weight segments D and thus prevent the same from falling out of the pocket 20. It is apparent, of course, that out-Ward movement of the Weight segments l) through the open face of the body 16 is prevented oiving to the shape of the guide rail 27.

lft is also apparent that the displacement of the Weights l) from out of the pocket will be prevented, by nails inadvertently driven through the stile l0, in that these Weights will frictionally bind on the rail 2T, when pressure is applied to the outer end thereof as is readily apparent.

lt also can be seen, of course, that when .veight segments D are associated with the body 16. Weight is added to the sash Weight A.

ln use of the improved sash Weight. the same is associated With the sash cord 13 by training cord about the pulley 18 and if the body 16 is not of suiiicient- Weight to balance the sashes l and 15, the Weight segments D are. added thereto by sliding the same Within the pocket. As ,many weight segments can be added to the body 16 as found necessary and if it is found that a number of the Weightl segments are not suflicient to properly balance the sashes, the Weight segments D can be removled and the relatively large Weight segment- C associated With the lower end of the body 16 after Which Weight segments D can be added thereto as found necessary.

From the foregoing description, it can be seen that an improved sash Weight has been provided. in which the Weight of the body thereof can be readily adjusted in a convenient and expeditious manner when found necessary or desirable.

Changes in details may be made Without departing from the spirit of this invention; but,

I claim:
